On of my friends recommended me Grand Alarms and received 4 months free monitoring for that. I decided that an alarm system would bring peace to my mind as i do a lot of business travelling. My wife stays up late at work quite frequently, too. I decided that $25 per months is not that much to keep my worries away. Apparently, their loyalty department does a good job keeping customers for long periods of time. I was told that my monitoring fee would go down to $18 after my subscription ended and i would receive discounts on my home insurance as well as some free stuff if i did some shopping at their home entertainment and automation department. I referred a couple of my friends and earned a couple of months free of charge. I thought it was worth it.
